No-Sugar Three Bean Salad

In a bowl, gently mix the garbanzo beans, kidney beans, green beans, green onions, and celery. In a separate bowl, whisk together the vinegar, oil, honey, mustard, garlic powder, black pepper, onion powder, and cayenne pepper. Pour dressing over the salad, and toss gently to coat. Cover, refrigerate at least 2 hours, and gently toss before serving.
